i'm trying to create a board in company-managed Jira Enterprise that combines multiple project boards from the same space together. I created a filter yet the system
Created board based on query of:
(type = Story AND Sprint IS NOT EMPTY) ORDER BY assignee DESC

It appears to create the board

However, it doesn't "stick", almost as though it "self" deleted. It presents the above for a hot-minute and then I get the following

In looking at Jira community and documentation, it is possible. What I can't determine is why it is deleting itself. Do we have to account for parity in sprint names across the individual project/boards?
Any thoughts on why this is happening? We have people assigned work across multiple boards within the same space and want to use one board during our stand-up meetings, etc.
